Dr Maheshi Wikramanayake, known to her patients as Dr Maheshi, is a consultant psychiatrist specialising in ADHD and autism spectrum disorder. She has more than 15 years of experience in psychiatry, in both the NHS and independent practice, in the assessment, diagnosis and treatment of a wide range of mental health conditions.
She has worked in several specialist services, including the National OCD Service, the Sussex ADHD Service and the Hertfordshire Community Eating Disorders Service. Her research at the National OCD Service looked at autism in people with OCD, and she received specialist training in diagnosing autism at the Cambridge CLASS Clinic.
She believes recovery should be led by the person themselves, and values an open and honest conversation with her patients. Because every person is different, she works with patients and their families on a plan built around their own needs, strengths and difficulties.
